Just as the other thread in this sub forum, I've had accidentally deleted a FLAC collection of mine and I went to recover it. Unlike the previous user most of my FLAC files turned out undamaged when recovering them but some were overwritten. Although I decided to recover the damaged files too, it went successfully and most of the FLAC files came intact. I played a few of them and I noticed one track that had a problem. When playing it in foobar (tried VLC also), at some random points it produces a unpleasant very loud screech (white-noise like). Now, as I had quite a few FLAC files in that collection, I would like to check them all for those errors, and preferably not through playback as that could be quite painful to the ears XDI tried to run the -t parameter in the CLI flac encoder on the file, but it reports no errors. Any suggestions on what to use to detect those mishaps? (if it can do it in batch mode that's a plus! )
